CPT® Code 33963

Extracorporeal membrane oxygenation (ECMO)/extracorporeal life support (ECLS) provided by physician; reposition of central cannula(e) by sternotomy or thoracotomy, birth through 5 years of age (includes fluoroscopic guidance, when performed)

Extracorporeal membrane oxygenation (ECMO) and extracorporeal life support (ECLS) are terms that refer to a medical procedure providing long-term support for patients with severe heart and lung dysfunction. This procedure involves the use of a machine that takes over the function of the heart and lungs by circulating blood outside the body through an artificial lung, where it is oxygenated before being returned to the bloodstream. The repositioning of central cannula(e) is a critical component of this procedure, particularly in pediatric patients from birth through 5 years of age. This repositioning is typically necessary when the initial placement of the cannula(e) needs adjustment due to anatomical considerations or changes in the patient's condition, such as primary left heart failure. The procedure is performed using a transthoracic approach, which may involve either a sternotomy (opening the chest through the sternum) or a thoracotomy (opening the chest through the ribs). Fluoroscopic guidance may be utilized during the repositioning process to ensure accurate placement of the cannula(e) within the blood vessels. This code, CPT® 33963, specifically applies to the repositioning of central cannula(e) in young patients, highlighting the specialized nature of care required for this age group.
